The aim of this study was to find out a formula for the feed conversion coefficient which is applicable solely farm pigs. performed by applying hybrid model growth animals in research not advanced, it published elsewhere. In only necessary equations were used. Feed complicated trait. usually used revised and transformed. three features analysed. reason distinct case studies that differs same we...

Selection was applied from 1964 to 1978 for increased weaning weight (WWL) or yearling weight (YWL) in two Hereford lines. An Angus line was maintained as an unselected control line (CL). Each line was maintained with 50 cows and four sires each year (two sires selected each year and used for 2 yr). Primary traits measured in the lines were birth weight (BW), preweaning daily gain (WDG), weanin...

Maternal nutrition during gestation is involved in the offspring's intestinal development and immunity. The aim of this study was to (1) determine the effects of maternal energy on intestinal digestion and absorption function in offspring, using pigs as a model; and (2) to evaluate the potential effect and mechanisms of maternal energy in modulating immune responses of lipopolysaccharide (LPS)-...

Seventy piglets with no access to creep feed were weaned at 28 d of age and fed on one of four diets based on either skimmed-milk powder (SMP), soya-bean-protein concentrate (SPC), soya-bean meal (SBM) or fish meal (FM). At 0, 3, 6 and 10 d after weaning, piglets were killed and the pancreas and digesta from stomach and small intestine were collected, freeze-dried and analysed for dry matter (D...

results in these children. Usually they are overfed and show normal oral intake and operation time was not delayed. As hypotheses, we believe that easier weaning of the cardiological ill children is caused by overfeeding supported by nutritional tubes. In clinical experience, all these children are fed by tube to gain weight for better operability [6] . Most of them do not loose much weight dur...

Seventeen Landrace X Large White primiparous sows that farrowed in August 1982 were fed ad libitum (AL, n = 8) or their intakes were restricted (R, n = 9) during lactation. Litter sizes were equalized after farrowing and pigs were not allowed creep feed. Pigs were weaned 23.8 +/- .4 d postpartum. On d 6, 12 and 20 postpartum, all sows were fasted for 16 h and blood samples were collected prior ...

The objective of this study was to estimate genetic parameters for pre-weaning traits of Braunvieh cattle raised under tropical conditions in Brazil. The weight and weight gain parameters were birth weight (BW, N = 9955), weight at 120 days of age (W120, N = 5901), weaning weight at 205 days (WW, N = 6970), weight gain from birth to 205 days (GAIN205, N = 6013), weight gain from birth to 120 da...

BACKGROUND There is paucity of information on the weaning of nasal CPAP (NCPAP) in preterm infants. As the weaning from NCPAP can be gradual or sudden, we wanted to determine which of the 2 methods was better. METHODS A prospective randomized trial was conducted to compare the success of weaning from NCPAP when using the sudden and gradual weaning methods in infants born ≤ 32 weeks. We also c...

Gestation length, birth weight, and weaning weight of F2 Nelore-Angus calves (n = 737) with designed extensive full-sibling and half-sibling relatedness were evaluated for association with 34,957 SNP markers. In analyses of birth weight, random relatedness was modeled three ways: 1) none, 2) random animal, pedigree-based relationship matrix, or 3) random animal, genomic relationship matrix. Det...
